Reclosable container for dipping and squeezing

ABSTRACT

A container is disclosed which includes a body shaped to define a reservoir. The body has a body flange coupled to a sidewall. The body flange forms a perimeter around an opening in the body, and the opening includes a spout and a dipping area. The container also includes a hinge region fixedly adhered to the body flange to form a hinge. The hinge region separates the lid into a first lid portion sealing the spout and a second lid portion sealing the dipping area, and the first lid portion rotates at the hinge to expose the spout and wherein the second lid portion rotates at the hinge to expose the dipping area.

BACKGROUND Technical Field

The present invention relates generally to containers, and more particularly to a reclosable container for storing edible substances that can be extracted from the container by dipping or squeezing.

Background

Disposable containers are commonly used to store condiments and other foodstuffs. The disposable containers generally assume two basic designs: tearable packets and disposable cups with removable lids. Tearable packets are small pouches generally formed from plastic or foil and contain single-use quantities of a condiment, such as ketchup, mustard, or soy sauce. The condiment stored within the packets are accessed by tearing one end of the packet and squeezing the contents out onto an item of food, or onto a surface to form a sufficiently large mass that food items can be dipped into. Disposable cups, as it relates to containers for storing condiments and other similar foodstuffs, are generally formed from plastic and have a relatively rigid body with a thin, flimsy lid that can be removed to expose a reservoir that food items can be dipped into. Most recently, the disposable plastic cups have evolved to permit access to the condiment via the traditional reservoir or by squeezing the condiment out from an integrated spout. The spout is exposed by tearing away a portion of the container.

Irrespective of whether traditional foil packets or plastic cups are used, these condiment containers are single-use containers ill-suited for saving an unused portion for later reuse, and in the case of disposable plastic cups that permit either dipping or squeezing, conventional designs do not permit a user to transition between dipping and squeezing. For example, once the reservoir is exposed, the squeezing capability is eliminated.

SUMMARY OF THE INVENTION

In a first embodiment, the disclosure describes a container that includes a body shaped to define a reservoir. The body has a body flange coupled to a sidewall. The body flange forms a perimeter around an opening in the body, and the opening includes a spout and a dipping area. The container also includes a hinge region fixedly adhered to the body flange to form a hinge. The hinge region separates the lid into a first lid portion sealing the spout and a second lid portion sealing the dipping area, and the first lid portion rotates at the hinge to expose the spout and wherein the second lid portion rotates at the hinge to expose the dipping area.

In a second embodiment, the disclosure describes a method for opening a container having a lid coupled to a body at a hinge region, wherein the hinge region separates the lid into a first lid portion and a second lid portion. The method includes separating a lid flange of the first lid portion from a body flange at a first end of the container; rotating the first lid portion in an arced path away from the body and towards a second end of the container; and securing the first lid portion to the second lid portion to achieve an opened state.

DETAILED DESCRIPTION

Novel aspects of the illustrative embodiments disclosed herein recognize the need for disposable containers that can offer access to its contents via squeezing or dipping, but also allow a user to transition between squeezing and dipping after the container has already been opened. Further, novel aspects of the container described herein also include design features that permit the disposable container to be securely reclosed to preserve an unused portion of the container's contents for subsequent reuse.

To facilitate the discussion and description of the various embodiments of the reclosable container, certain descriptive conventions may be used to describe the relative position or location of container features. For example, the reclosable container described herein is formed from a body shaped to define a reservoir. Attached to the body is a lid that seals the reservoir to preserve and maintain the contents of the container. The lid may be described as the top of the container or located above or upwardly from another part of the container, such as the body. In addition, the body may be described as the bottom of the container, or located below, underneath, or downwardly from another part of the container, such as the lid. Thus in some embodiments the body has a planar bottom surface and a sidewall extending upwardly from the bottom surface to a body flange that is adhered to a lid flange.

The reclosable container has a spout and a dipping area that provides access to the container's contents via squeezing or dipping, respectively. In a non-limiting embodiment, the spout is accessed from one end of the container and the dipping area is accessed from the opposite end of the container.

FIG. 1 is top view of a container in accordance with an illustrative embodiment. The reclosable container 100 has a lid 102 affixed to a body shaped to define a reservoir that stores condiments, like ketchup, mustard, or salsa, or other suitable comestibles. The contents of the container 100 may be accessed by exposing a spout and squeezing the container 100 to force the contents out of the spout. Alternatively the contents may be accessed by exposing a dipping area, which would allow food items to be dipped into the container 100. Novel aspects of the container 100, which will be discussed in more detail below, include a novel lid that can be opened without having to tear through a portion of a rigid container, a latching feature that enables the lid to maintain an open configuration for ease of access, and a mechanical seal that facilitates resealing of the container 100 so that any unused portion may be saved and reused.

In this illustrative embodiment, the lid 102 is depicted as having an oblong shape that is characterized by a length 104 longer than a width 106. The lid 102 also has a first end 108 and a second end 110 opposite to the first end 108. The longitudinal sides are curved outwardly so that the lid is generally the widest halfway between the first end 108 and the second end 110. Extending across the width of the lid 102 is a hinge region 112, which is a planar area that permits the lid 102 to flex along a predetermined axis. For example, the first end 108 of the lid 102 may rotate in an arced path in a direction towards the second end 110. Likewise, the second end 110 of the lid 102 may rotate in an arced path in a direction towards the first end 108. The rotation of the lid 102 is limited to the hinge region 112 by other three-dimensional structural features, which provide rigidity that opposes flexation and rotation, as described in more detail below.

The hinge region 112 separates the lid 102 into a first lid portion 114 and a second lid portion 116. The first lid portion 114 corresponds with the first end 108 of the lid 102 and seals the spout of the container 100. The second lid portion 116 corresponds with the second end 110 of the lid 102 and seals the dipping area of the container 100. In this illustrative embodiment in FIG. 1, the first lid portion 114 houses a first latching feature 118, and the second lid portion 116 houses the second latching feature 120 that is configured to receive the first latching feature 118. The first latching feature 118 and the second latching feature 120 may be used to mechanically couple the first lid portion 114 to the second lid portion 116 after the lid 102 is rotated at the hinge region 112.

In this illustrative embodiment, the first latching feature 118 is a square-shaped protrusion projecting upwardly from the lid 102, away from the body, and the second latching feature 120 is a recessed trough aligned with its ends pointing towards the first end 108 and the second end 110. The trough has dimensions that permit the trough to securely, but removably engage the protrusion located on the first lid portion 114. The trough-like shape of the second latching feature 120 should have a length that is sufficiently long so that the first latching feature 118 and the second latching feature 120 can engage each other regardless of which lid portion is being opened. For example, when the first lid portion 114 is opened and rotated toward the second lid portion 116, the first latching feature 118 engages the second latching feature 120 at an end closest to the hinge region 112. Likewise, when the second lid portion 116 is opened and rotated toward the first lid portion 114, the first latching feature 118 engages the second latching feature 120 at an opposite end of the trough.

However, in other embodiments, the first latching feature 118 and the second latching feature 120 may have different shapes or modes of operation. For example, the first latching feature and the second latching feature may have an analogous form and function as traditional snap buttons used for clothing.

Lid flange 122 is a generally planar area defining a perimeter around the lid 102. In one embodiment, the lid flange 122 is coextensive with the body flange 132 so that the lid flange 122 may be adhered to a body flange 132 to seal the contents inside a reservoir of the container 100. In one embodiment, selected portions of the lid flange 122 are fixedly adhered to the body flange 132 so that the lid 102 cannot be removed without deforming or destroying the container 100. Other portions of the lid flange 122 are removably adhered to the body flange 132 of the body so that the lid 102 can be partially detached from the body 130 to expose either the spout or the dipping area. As can be seen in FIG. 1, the lid flange 122 is fixedly adhered to the body flange 132 at the hinge region 112 to form a hinge that allows the first end 108 to rotate towards the second end 110 and vice versa. In addition, portions of the lid flange 122 are removably adhered to the body flange 132 at the removably adhered regions 124 a and 124 b.

The lid flange 122 may be fixedly adhered to the body along the hinge region 112 using any conventional means. In a preferred embodiment, the hinge region 112 is adhered to the body flange 132 by an ultrasonic weld. Likewise, the lid flange 122 may be removably adhered to the body flange 132 at the removably adhered regions 124 a and 124 b by conventional means, including but not limited to food grade adhesives, pressure sensitive adhesives, or heat seals. In one embodiment, the adhesive adhering the lid flange 122 to the body flange at the removably adhered regions 124 a and 124 b should have sufficient adhesive properties to form a hermetic seal that preserves the integrity of the contents stored within the container 100, but should not prevent a user from being able to detach the lid 102 from the body. Thus, in one embodiment, the reclosable container 100 has a first hermetic seal securing the first lid portion 114 to the body flange 132 and a second hermetic seal securing the second lid portion 116 to the body flange 132.

The placement of the hinge region 112 dictates the relative sizes of the spout and the dipping area. A smaller spout results in a more controlled release of the contents and a larger dipping area facilitates dipping of food pieces into a reservoir of the container 100. Thus, in this illustrative embodiment of FIG. 1, the hinge region 112 is located closer to the first end 108 of the lid so that the spout is smaller than the dipping area. However, in alternate embodiments the hinge region 112 may be located further towards the second end 110 of the lid 102, which would increase the size of the spout and decrease the size of the dipping area. Such a configuration may be preferred in the event that the contents of the container 100 may include chunks of food pieces, such as salsa.

To facilitate the task of detaching the lid 102 to expose either the dipping area or the spout, portions of the lid flange 122 may be un-bonded to the underlying body flange at specifically located regions. A first non-bonded region 126 a may be located at the first lid portion 114 and a second non-bonded region 126 b may be located at the second lid portion 116. Each of the non-bonded regions should have an area sufficiently large to enable a user to peel back a corresponding portion of the lid flange 122 and to grasp the non-bonded region to initiate the process of detaching the lid 102 from the body 130. The location of the non-bonded regions 126 a and 126 b should be deemed exemplary and non-limiting. For example, second non-bonded region 126 b at the second end 110 of the lid 102 is depicted along one of the curved edges. In another embodiment, the second non-bonded region 126 b may be located on the opposite edge of the lid 102. In yet another embodiment, the second non-bonded region 126 b may be oriented along the second end 110 to span the width 106 of the lid 102 so that the lid 102 is symmetric.

Although it is not evident from FIG. 1, the lid 102 includes at least one mechanical seal that coincides with either removably adhered regions 124 a, 124 b, or both. Thus, the at least one mechanical seal may secure at least one of the first lid portion 114 or the second lid portion 116 to the body 130. In an embodiment where the container 100 includes a first hermetic seal located at removably adhered region 124 a and a second hermetic seal at removably adhered regions 124 b, the mechanical seal is coextensive with the first hermetic seal and the second hermetic seal. A mechanical seal differs from an adhesive seal in that the mechanical seal is formed from the mechanical coupling of structural features on opposing, operative surfaces. Tupperware® containers, Ziploc® bags, and mason jars with screw top lids are all non-limiting examples of containers with mechanical seals. The mechanical seal serves two primary functions. First, the three-dimensional nature of the mechanical seal improves the structural integrity of the container, which helps to resist forces that would otherwise deform the container 100. Second, the mechanical seal provides a reliable means of resealing the container 100 once the hermetic seals have been compromised. In the illustrative embodiments discussed herein, the mechanical seal is formed by the engagement of a recessed sidewall extending from the lid 102 and an interior surface of the sidewall 136. The mechanical seal implemented in container 100 will be discussed in more detail in FIGS. 5-7.

The lid 102 is generally rigid, a characteristic that may be attributed at least in part due to the various structural features incorporated thereon. For example, the first latching feature 118 and the second latching feature 120 should be sufficiently rigid so that they can be secured together and allow the container to be maintained in an open configuration. Likewise, the recessed sidewall imparts further rigidity. Manufacturing techniques may also result in portions of the lid 102 being thicker, and thus more rigid than others. For example, the lid 102 may be created by extruding or thermoforming a flat, plastic blank to achieve a three-dimensional form factor. The lid flange 122 and the second latching feature 120 may be exposed to less stretching and deformation, resulting in surfaces that may be thicker and more rigid. In contrast, sunken surfaces 128 a and 128 b may be formed by stretching the plastic blank, resulting in areas that are comparatively thinner and less rigid. The sunken surfaces 128 a and 128 b can be seen in more detail in the perspective view of FIG. 4.

In one embodiment, the lid 102 is formed from food grade plastic using conventional manufacturing techniques. For example, the lid may be formed from HDPE or PET/PETE, and formed by thermoforming or injection molding.

FIG. 2 is a side view of a reclosable container in accordance with an illustrative embodiment. The container 100 is formed from a lid 102 attached to a body 130. In particular, the lid 102 includes a lid flange 122, which defines a plane that forms the uppermost surface of the container 100. The lid flange 122 is depicted as sealed against the body flange 132. A sidewall 136 extends from body flange 132 to the bottom surface 134, defining a reservoir enclosed within the body 130.

Projecting upwardly from the lid 102 and away from the body 130 is a first latching feature 118. The second latching feature 120, which is recessed below the plane of the lid flange 122, is obscured in this side view of FIG. 2 by the sidewall 136 but can be seen more clearly in the perspective view of FIG. 4.

The lid 102 includes a hinge region 112 that divides the lid into a first lid portion 114 and a second lid portion 116. In this illustrative embodiment, the hinge region 112 is located closer to the first end 108 to form an appropriately sized spout and dipping area. In addition, the lid 102 is fixedly attached to the body 130 at the hinge region 112.

In this illustrative embodiment in FIG. 2, the bottom surface 134 is smaller than the opening sealed by the lid 102. As a result, the interior angle between the sidewall 136 and the bottom surface 134 is obtuse, which is better suited for dipping. The obtuse angle eliminates the deadzones located in the immediate vicinity of corners formed by the intersection of two orthogonal surfaces, or two substantially orthogonal surfaces. However in an alternate embodiment, the bottom surface 134 may have an area that is the same or substantially the same as the area of the opening in the body 130 that is surrounded by the body flange 132 so that sidewall 136 is orthogonal or substantially orthogonal to the bottom surface 134.

FIG. 3 is a bottom view of a reclosable container in accordance with an illustrative embodiment. The reclosable container 100 has a body 130 that includes a sidewall 136 extending upwardly from the bottom surface 134 to the body flange 132. The body flange 132 is adhered to the lid flange 122 to seal the opening of the body 130. In particular, the body flange 132 fixedly adhered to the lid flange 122 at the hinge region 112, which forms a dual-sided hinge that allows the first lid portion 114 and the second lid portion 116 to rotate along a predefined axis. In addition, the body flange 132 is removably adhered to the lid flange 122 at the removably adhered regions 124 a and 124 b. As previously mentioned, hermetic seals may be provided at the removably adhered regions 124 a and 124 b. If present, the hermetic seals must be broken before the container 100 is opened for the first time. As will be discussed in more detail below, the removably adhered regions 124 a and 124 b may be coextensive with a mechanical seal, which is not evident from this perspective.

In this illustrative embodiment, a non-bonded region is located at or associated with each end of the container 100 to facilitate the task of detaching the lid 102 from the body 130. As can be seen, non-bonded region 126 a is located at the first end 108 of the container 100 and another non-bonded region 126 b is located along one of the curved sides of the container 100 and adjacent to the second end 110.

FIG. 4 is a perspective view of a reclosable container in accordance with an illustrative embodiment. The reclosable container 100 includes a lid 102 and a body 130 shaped to define a reservoir for storing foodstuff. The body 130 includes a body flange 132 coupled to a sidewall 136 that may optionally transition into a bottom surface, such as bottom surface 134 in FIG. 2. The body flange 132 forms a perimeter around an opening in the body 130 which has a spout and a dipping area.

In this illustrative embodiment in FIG. 4, the lid 102 includes a lid flange 122 that defines an upper surface of the container 100, and a set of sunken surfaces 128 a and 128 b that are connected to the lid flange 122 by a recessed sidewall 142. The recessed sidewall 142 is formed when the lid 102 is shaped to include one or more sunken surfaces 128 a and 128 b. In addition, the recessed sidewall 142 has a length that is coextensive with the removably adhered regions 124 a and 124 b and provides additional surface area for the lid 102 to seal against the body 130. Engaging the recessed sidewall 142 with the body 130 forms a mechanical seal that can be used to reclose the container 100 after the hermetic seal is compromised. The mechanical seal is formed from the coupling of opposing operative surfaces. In one embodiment, an interior surface of the sidewall 136 forms one operative surface of the mechanical seal and an interior surface of the recessed sidewall 142 of the lid 102 forms another operative surface of the mechanical seal. In some embodiments, the opposing operative surfaces include complementary sealing structures that can secure the surfaces together, as can be seen in more detail in FIGS. 5-7.

The first lid portion 114 includes a first latching feature 118 and the second lid portion 116 includes a second latching feature 120 configured to receive the first latching feature. In this illustrative embodiment, the first latching feature 118 is a protrusion extending upwardly from the lid 102, and the second latching feature 120 is a trough projecting upwardly to receive the protrusion, but which is recessed below a plane defined by the lid flange 122. In one embodiment, the trough is recessed into a platform 138 that has a base connected to the sunken surface 128 b and an upper surface that corresponds with the plane defined by the lid flange 122. The shape of the platform 138 is exemplary and should not be interpreted as limiting. Thus, in another embodiment, the platform 138 may have rounded edges, or may lack the gradual taper at the distal end.

FIG. 5 is a perspective view of the reclosable container 100 with an exposed spout in accordance with an illustrative embodiment. The reclosable container 100 has a body 130 shaped to define a reservoir, the contents of which may be accessed via the spout 140. The body 130 includes a body flange 132 that forms a perimeter around an opening in the body 130, which includes the spout 140 and a dipping area. Thus, the spout 140 is a part of the opening from which the contents may be squeezed out of the container 100.

The spout 140 may be exposed by peeling back the first end 108 of the lid 102 and detaching the lid flange 122 of the first lid portion 114 from the corresponding portion of the body flange 132. In some embodiments, the detaching process is facilitated by the presence of the first non-bonded region 126 a which is easily separated from the body flange 132 and usable as a graspable tab. Sufficient force should be applied by pulling the lid 102 at the first end 108 of the lid 102 to break the hermetic seal, but also to overcome the sealing forces imparted by the mechanical seal that also seals the spout 140. A mechanical seal is formed when an operative surface of the lid 102 engages an operative surface of the sidewall 136 to provide a seal that secures the lid 102 to the body 130. The opposing operative surfaces, when brought together, form a mechanical seal that prevents the stored foodstuff from seeping out. In this illustrative embodiment, the operative surface of the first lid portion 114 is an interior surface of the recessed sidewall 142 that engages an interior surface of the sidewall 136 when the first lid portion 114 is in the closed configuration. Likewise, the operative surface of the sidewall 136 is the portion of the interior surface of the sidewall 136 which engages the recessed sidewall 142 when the first lid portion 114 is in the closed configuration. In addition, each of the operative surfaces may include a sealing structure that allows the operative surfaces to be secured together. For example, in one embodiment, the operative surface of body 130 includes a continuous, convex projection 144 a around a perimeter of the opening, below the body flange 132. The operative surface of the first lid portion 114 includes a horizontal recess 144 b sized to receive the convex projection 144 a. In operation, the mechanical seal at the first end of the container is engaged by pressing the first lid portion 114 against the body 130 with sufficient force to cause the convex projection 144 a to engage with the horizontal recess 144 b in recessed sidewall 142.

The first lid portion 114 may be secured in the open position by causing the first latching feature 118 and the second latching feature 120 to engage each other. In this illustrative embodiment where the first latching feature 118 is a protrusion and the second latching feature 120 is a trough that is shaped and sized to receive the protrusion, the protrusion is pressed into the trough. In some embodiments, frictional forces are sufficient to securely engage the first latching feature 118 and the second latching feature 120. In another embodiment, the first latching feature 118 and the second latching feature 120 may have complementary shapes or features that promote latching. For example, in the embodiment where the first latching feature 118 is a protrusion and the second latching feature 120 is a trough, the first latching feature 118 may be tapered so that the base is smaller than its distal end. Additionally, the trough may be sized oppositely so that the trough has two opposing sides that are closer together the top and wider apart at the base. In either embodiment, with the spout 140 exposed, the contents within the container 100 may be squeezed out by applying a compressive force to the lid 102 and the bottom surface 134 of the body 130.

FIG. 6 is a perspective view of the reclosable container depicting an exposed dipping area in accordance with an illustrative embodiment. The reclosable container 100 has a body 130 shaped to define a reservoir, the contents of which may be accessed via the dipping area 148. The body 130 includes a body flange 132 that forms a perimeter around an opening in the body 130 which includes the spout and the dipping area 148.

The second lid portion 116 may be detached from the body 130 to expose the dipping area 148 by grasping a portion of the lid flange 122 at the second non-bonded region 126 b and peeling the second lid portion 116 away from the body 130 in an arced trajectory so that the second end 110 of the lid 102 is brought in a direction towards the first end 108 of the lid 102. Sufficient force is required to break the hermetic seal if the container has not yet been opened, and also to uncouple the mechanical seal that secures the lid 102 to the body 130 to seal the dipping area 148.

The mechanical seal is formed when an operative surface of the lid 102 engages an operative surface of the sidewall 136. In this illustrative embodiment, the operative surface of the second lid portion 116 is an interior surface of the recessed sidewall 142 that engages an interior surface of the sidewall 136 when the second lid portion 116 is in the closed configuration. Likewise, the operative surface of the sidewall 136 is the portion of the interior surface of the sidewall 136 which engages the recessed sidewall 142 when the second lid portion 116 is in the closed configuration. In addition, each of the operative surfaces may include a sealing structure that allows the operative surfaces to be secured together. For example, in one embodiment, the operative surface of body 130 includes a continuous, convex projection 144 a around a perimeter of the opening, below the body flange 132. The operative surface of the second lid portion 116 includes a horizontal recess 144 c sized to receive the convex projection 144 a. In operation, the mechanical seal at the second end 110 of the container is engaged by pressing the second lid portion 116 against the body 130 with sufficient force to cause the convex projection 144 a to engage with the horizontal recess 144 c in recessed sidewall 142.

The second lid portion 116 may be maintained in the open configuration to continuously expose the dipping area 148. The open configuration may be achieved by securing the second lid portion 116 to the first lid portion 114 by pressing the second latching feature 120 against the first latching feature 118 to cause the protrusion to engage the trough.

FIG. 7 is a cross-sectional view of the reclosable container taken along line 7-7 in FIG. 4. The reclosable container 100 has a body 130 shaped to define a reservoir for storing foodstuff 200. The body 130 includes a body flange 132 coupled to a sidewall 136 that optionally transitions into bottom surface 134. The body flange 132 forms a perimeter around an opening in the body 130 which includes a spout 140 and a dipping area 148. More particularly, the hinge region 112 of the lid 102, which is fixedly adhered to an underlying region of the body flange 132, divides the opening into the spout 140 and the dipping area 148.

The first lid portion 114 seals the dipping area 148 and the second lid portion 116 seals the spout 140. In this illustrative embodiment, the first lid portion 114 and the second lid portion 116 are shown in the partially open configuration to illustrate the manner in which the hinge region 112 allows the opposing ends of the lid 102 to rotate to open and close the container 100. Rotation of the first lid portion 114 and the second lid portion 116 to open the container 100 obviates the need to tear through any portion of the container 100, which is required to open prior art containers.

The dipping area 148 may be sealed by rotating the second lid portion 116 downward to cause the lid flange 122 to engage the body flange 132. Sufficient force is applied to the second lid portion 116 to cause the operative surface of the recessed sidewall 142 to engage the operative surface of the sidewall 136. In particular, the closing force should be sufficient to cause the convex projection 144 a to engage with the horizontal recess 144 c, forming a mechanical seal that secures the second lid portion 116 to the body 130.

Similarly, the spout 140 may be sealed by rotating the first lid portion 114 downward to cause the lid flange 122 to engage the body flange 132. Sufficient force is applied to the first lid portion 114 to cause an operative surface of the recessed sidewall 142 to engage the operative surface of the sidewall 136.
